Now lets see.. My crit rate as fire is a bit over 35% atm so that makes me fireball crit ~42% so that would make chances of 10, 15 or 20 non crits in a row 0.58^10= 0,004, 0,58^15=0,0002 and 0,58^20= 0,000018..

So yeah gl with getting more than once in a fight when on average its not even likely to happen once in a fight..
